3. Apium prostratum Labillardière ex Ventenat (1804 : t. 81).

Lectotype (designated here):— FRANCE. Jard. de Malm. Ventenat s.n. (G00359756!).

Notes:— Apium prostratum Labillardière (1800) is a nomen nudum. In 1804 Ventenat described A. prostratum as one of the species that grew at the “Jardin de la Malmaison”, and indicated that the species is native from “la Nouvelle Hollande ” ( Australia). The original material corresponds to a collection from Ventenat from plants cultivated at Malmaison´s Garden. Short (1979) indicates that the holotype of Apium prostratum Ventenat is housed at P, however, the material that we have found at P corresponds to gatherings from Australia collected by Labillardière (e.g. P00307178) and therefore are not part of the original material of Ventenat´s name. At G, however, we have found two accessions of the original material: G00359756 and G00478844. The latter, is at the same sheet with other two gatherings (G00478843 and G00478846) and apparently lacks material asscociated with the label by Ventenat, or it is unlikely to unequivocaly assign any of the specimens to it. On the contrary, G00359756 is the only specimen on the sheet and matches the protologue in the description and label indications, and was therefore designated as lectotype of Apium prostratum Ventenat.
